SAR Arms K2-45 | .45 ACP | 4.7in Stainless | 14-Round

The SAR Arms K2-45 is a full-size, single-action pistol chambered in .45 ACP with a 4.7-inch stainless barrel and stainless frame. It ships with an accessory rail and is fitted with a beavertail for higher-hand placement. For a compatible optic under $1,000, consider a compact footprint red-dot such as a Trijicon RMR or a Holosun compact model for fast target acquisition without overcutting the slide.

Typical uses for this pistol include precision range work and competition/practice where the .45 ACP’s ballistics and the full-size platform’s sight radius are beneficial.

This K2-45 blends a traditional single-action trigger package with a stainless full-size frame and an accessory rail for lights or lasers. The combination of a 4.7-inch barrel and a full-size grip makes it well suited to controlled, deliberate shooting from the range and for competition-practice sessions, where follow-up-shot control and sight radius matter. The stainless construction resists corrosion while the polymer grip reduces felt mass, producing a balanced, confidence-inspiring handling experience for shooters who value straightforward function and serviceable ergonomics.
